Description

Technical Field

[0001] This utility model belongs to the field of ignition core technology, and specifically relates to a high-temperature resistant semiconductor ignition core. Background Technology

[0002] The hot surface igniter with a flat plate structure is used in sealed gas ovens, gas dryers, and boiler equipment. It is resistant to oxidation at high temperatures and has high efficiency and safety performance when connected in series with a bimetallic gas valve. At the same time, it solves the problem of deflagration and explosion caused by the large amount of gas emitted after ignition due to poor ignition of ordinary igniters. Its process is to obtain a high-density, low-resistivity product through reaction sintering and recrystallization.

[0003] Existing silicon carbide ignition cores have a fixed structure, and their power parameters cannot be adjusted after production. Gas appliances with different power requirements need to be equipped with corresponding dedicated ignition cores, forcing manufacturers to stock multiple specifications of ignition cores, increasing inventory costs and management complexity. At the same time, the structural design of traditional ignition cores lacks flexibility, cannot adjust power according to changes in actual usage scenarios, has poor adaptability, and is difficult to meet diverse usage needs.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is a high-temperature resistant semiconductor ignition core, including an ignition core body. The ignition core body is an integrally molded structure made of silicon carbide. A central slot is opened through the ignition core body along its length. The length of the central slot is selectively set according to the power requirements. The power of the ignition core body decreases as the length of the central slot increases. The thickness of the ignition core body is 1.6mm, and the width of the central slot is 1mm.

[0006] The ignition core body is flat and includes a first section, a transition section and a second section connected in sequence. The width of the first section is greater than the width of the second section. The transition section has a chamfered curved surface structure and a central slot is opened in the middle of the first section, the transition section and the second section.

[0007] The total length of the ignition core body is 45mm, the second section is 30mm long and 4mm wide, and the first section is 9mm wide.

[0008] The first segment can be connected to the conductive wire.

[0009] This utility model has the following beneficial effects: This invention achieves flexible power adjustment by opening an adjustable-length central slot in the ignition core body. The longer the central slot, the lower the power of the ignition core body. The length of the central slot can be selectively set during the production process according to the power requirements of different gas equipment. At the same time, the ignition core body is integrally molded from silicon carbide material, which has high structural strength, excellent high temperature resistance and oxidation resistance, long service life, and can withstand extreme temperature changes without cracking, further improving the reliability of use.

[0010] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-2 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0014] Example 1, please refer to Figure 1 , Figure 2 As shown: A high-temperature resistant semiconductor ignition core includes an ignition core body, which is an integrally molded structure made of silicon carbide to ensure structural strength and thermal and electrical conductivity. The ignition core body has a central slot 1 extending through it along its length. The length of the central slot 1 is selectively set according to power requirements. The power of the ignition core body decreases as the length of the central slot 1 increases, thereby achieving flexible power adjustment. The ignition core body is flat and includes a first section 2, a transition section 3, and a second section 4 connected in sequence. The width of the first section 2 is greater than the width of the second section 4. The transition section 3 has a chamfered curved surface structure, which can improve the structural stability. The central slot 1 is opened in the middle of the first section 2, the transition section 3, and the second section 4. The thickness of the ignition core body is 1.6mm, the total length of the ignition core body is 45mm, the width of the central slot 1 is 1mm, the length of the second section 4 is 30mm and the width is 4mm, the width of the first section 2 is 9mm, and the first section 2 can be connected to a conductive wire to connect to an external device to heat the ignition core body.

[0015] When a high-power ignition core is required, select the shorter length of the middle slot 1. In this case, the ignition core power is higher, the hot resistance is 32-33 ohms, the cold resistance is 140-155 ohms, it is compatible with 220V working voltage, and is suitable for high-power gas furnaces.

[0016] Example 2: When a medium-power ignition core is required, adjust the length of the middle slot 1. At this time, the ignition core power is moderate, the hot resistance is 30-31 ohms, the cold resistance is 100-139 ohms, and it is compatible with 110-220V working voltage, which is suitable for water heaters.

[0017] Example 3: When a low-power ignition core is required, a longer central slot 1 is set. In this case, the ignition core power is lower, with a hot resistance of 28-29 ohms and a cold resistance of 69-99 ohms. It is compatible with 110V working voltage and is suitable for small ovens.
